CVE-2026-84823

HIGH CVSS 3.1: 7.1 EPSS 0.34%
Updated Oct 16, 2026
Red Hat
Parameter Value
CVSS 7.1 (HIGH)
Type CWE-22 (Path Traversal)
Vendor Red Hat
Public PoC No

A flaw was found in WildFly. A user with the `Monitor` role, which is the lowest standard Role-Based Access Control (RBAC) role, can exploit a path traversal vulnerability in the `take-snapshot` operation. By manipulating the `name` parameter, this user can write a copy of the server configuration to an arbitrary location.

This allows the `Monitor` role to read back the server configuration, including sensitive credentials, which would otherwise be restricted by RBAC, leading to information disclosure.
